FusMix
Scalable 4K fusion mixer for SDI, ST 2110, NDI, and NVI.
Integrated switching, streaming, recording, audio mixing, graphics, and playback in a compact production system for studio, OB van, and live events — built on the distributed RenderFlow architecture and FPGA embedded hardware.
Overview
FusMix is a scalable 4K live production switcher platform supporting SDI, ST 2110, NDI, and NVI workflows. Built on a distributed RenderFlow architecture and FPGA-based embedded hardware, it provides flexible signal processing, multi-bus rendering, and advanced live production capabilities for broadcast, sports, studio, and large-scale event production — switching, streaming, recording, audio mixing, graphics, and playback integrated in one compact system.
Challenge
4K multi-camera production keeps outgrowing the switcher: more inputs, more formats, more layers — while the gallery still expects one operator surface and zero dropped frames.
Single-device ceilings
A fixed-capacity switcher caps inputs and rendering; when the event grows, the production has to swap hardware instead of scaling it.
Four signal worlds
SDI, ST 2110, NDI, and NVI sources arrive in the same production and have to be switched together, frame-accurately.
A rack of point tools
Player, audio mixer, multiviewer, and graphics as separate devices multiply cabling, sync points, and failure modes.
Mission-critical reliability
Sports and large events run live once; the switching core needs hardware-grade stability and redundancy.
Solution
FusMix scales by adding rendering and inputs instead of replacing the switcher.
Key Features
- Unified switching — SDI / ST 2110 / NDI / NVI in one mixer, with 4K and HD full frame-rate processing and frame-level seamless hardware switching — compliant with ST 2022-7 and NMOS IS-04/05.
- RenderFlow architecture — Distributed parallel multi-bus rendering eliminates single-device performance bottlenecks, with scalable input expansion and rendering via cascading at ultra-low end-to-end latency.
- M/E and compositing — 2-level M/E with 8+ video layers per level and unlimited cascading capability, plus 2 external keys, 4 internal keys, and 6+ graphics overlay layers.
- All-in-one workflow — Integrated DDR player, 16-channel audio mixer, and 4K multiviewer supporting 16+ windows, with a built-in graphics engine for subtitles, logos, and on-air graphic playout.
- Reliable hardware — FPGA-powered embedded architecture with built-in frame synchronizer and redundant power for mission-critical live production.
Hardware Configurations
Three chassis cover the range, from the 4U flagship to the 2U IP-lean build.
- FMS-2246-Pro — 4U chassis — 24 channels of 12G-SDI input, 20 channels of ST 2110, 18 channels of NVI/NDI, and 8 × 16-channel AES audio input.
- FMS-2244-Base — 2U chassis — 24 channels of 12G-SDI input, 8 channels of NVI/NDI, and 8 × 16-channel AES audio input.
- FMS-2126-IP — 2U chassis — 12 channels of 12G-SDI input, 10 channels of ST 2110, 8 channels of NVI/NDI, and 4 × 8-channel AES audio input.
Scenarios
- Live sports — Multi-camera 4K live production with high-density signal processing, M/E compositing, and real-time graphics.
- Large-scale events — Complex live events requiring scalable switching, multi-layer composition, and reliable hardware operation.
- OB vans — Flexible SDI/IP signal integration and redundant hardware architecture on the truck.
- Studios — Broadcast studio workflows with integrated graphics, audio mixing, multiview monitoring, and playout.
- Reality shows — Multi-camera production with advanced compositing, graphics packaging, and real-time switching.
Result
A switching platform that grows with the production — four signal families on one bus, rendering that cascades instead of capping out, and the player, mixer, multiviewer, and graphics already inside the frame.
